Abstract: SEARCH RADAR                         Abstract A pulsed doppler search radar is disclosed in which range, bearing, and radial velocity are made available for display. The radar incorporates a capacitor matrix correlator and an improved method of range determination utilizing passive decoding circuitry and sequential unblanking of the capacitor correlator matrix drivers where required. Moreover, a passive implementa-tion of the doppler direction algorithm is provided in which a summing circuit is implemented on the same printed circuit board utilized to form the capacitor correlator matrix. The capacitor matrix correlator and doppler direction summing circuit are manufactured through the use of face-to-face printed cir-cuit boards having overlying sections patterned and registered so as to form the capacitive elements thereby simplifying the manufacture of the doppler correlator and doppler direction circuits.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention concerns a shunt or series regulating apparatus for controlling the current supplied to a bus line from a plurality of power sources.  The apparatus comprises error detectors, dump switches; comparators with positive feedback and capacitor. The error detectors compare the bus voltage to a reference voltage and produce an error signal representing the deviation between these two voltages.          The dump switches are each connected in parallel with a respective power source, and each is responsive to a control signal for switching from a OFF state to a ON state thereby to shunt the current delivered by the power source to the bus line.  The comparators are associated to a respective power source and each comparator has a first input connected to the output from the error detector, a second input connected to a respective reference voltage level, and an output connected to the control input of a respective of the dump switches for applying a control signal thereto which is proportional to the difference between the error signal and the reference voltage level.  The positive feedback circuits are each connected between the output of the respective power source and the second input of the corresponding comparator for superimposing a signal to the reference voltage level, thereby to set two operation thresholds for the comparator, such that each dump switch is allowed to switch cyclically between its two states, thereby to allow the current from the corresponding power source to be fed into the bus line when the dump switch is OFF and to short the power source when the dump switch is ON.  The capacitor is connected between the bus line and the ground in order that its charge follows at any time the variation of the total current drawn from the plurality of power sources into the bus line such that one switch at a time is caused to switch cyclically between its two states and such that the switches are caused to switch cyclically one after another as the value of the error signal is increasing.

Abstract: DIGITAL SIGNAL PHASE SHIFTING SYSTEM            Abstract Of The Disclosure A digital signal phase shifting system is disclosed which comprises a timing signal generator producing cyclic digitally coded timing signals; a first system output signal generator capable of decoding the timing signals and producing first system output signals in response to the occurrences of predetermined timing signals; a second system output signal generator capable of decoding digitally coded signals and producing a group of second system output signals in response to operation of the timing signal generator; and a setting device adjustable by the user to condition the second system output signal generator to shift the phase of the group of second system output signals.          The disclosed system includes alternative constructions for phase shifting a group of system output signals.  In one construction pairs of the output signals of the group are produced by respective binary coded signal decoder units and a binary adder is connected between the decoder units and the timing signal generator.  The timing signals, which are binary coded, are input to the adder and the adder output is fed to the decoder units.  The setting device is effective to input a binary coded signal to the adder so that the adder output signal is reflective of  the sum of the input timing signal and the setting signal.  By changing the setting signal valve the entire group of output signals from the decoder units is phase shifted.          In another construction the binary coded timing signals are input directly to a decoder unit which produces plural output signals.  The decoder unit is formed by a pair of digital comparators having settable inputs.  A binary adder has its output connected to the settable input of one comparator and the setting device is connected both to the adder input and the settable input of the other comparator. A second adder input is settable by the used.  The output signal pulses are simultaneously phase shifted by adjusting the setting device.
